    4. Adults with IBD over the age of 50 should consider vaccination against herpes zoster, including certain subgroups of immunosuppressed patients.
    5. Adults with IBD should be assessed for prior exposure to varicella and vaccinated if naive before initiation of immunosuppressive therapy when possible.

    7. Adolescents with IBD should receive meningococcal vaccination in accordance with routine vaccination recommendations.
    8. Household members of immunosuppressed patients can receive live vaccines with certain precautions.
    9. Adults with IBD should receive age-appropriate vaccinations before initiation of immune suppression when possible.
